Abstract

Abstract 1. 1. The following caratenoids were isolated and identified from Emerita analoga: α-carotene, β-carotene, echinenone, canthaxanthin, zeaxanthin, diatoxanthin, alloxanthin and astaxanthin. 2. 2. The relative abundance and concentration of carotenoids in monthly samples of adults, carapace, ovaries, eggs and blood was measured. 3. 3. Incorporation of 14C-labelled carotenoids of the alga Ulva into Emerita provides evidence for the metabolism of ketocarotenoids from ingested β-carotene by a decapod crustacean. 4. 4. An orange carotenoprotein was found in ovaries, eggs and blood. 5. 5. There was no evidence for the utilization of carotenoids during egg development. 6. 6. The possible role of carotenoids in reproduction of Emerita is discussed.
